Abstract

In the analysis of the reaction e⁺e^-→e⁺e^-K_S⁰K_s⁰ clear evidence for exclusive γγ→f₂^′ resonance production is observed. The product Γ_γγ ·B(f₂^′→K {Mathematical expression}) is measured to be 0.10_-0.03-0.02^+0.04+0.03 keV independent of an a priori assumption on the helicity structure. Our data are consistent with a pure helicity 2 contribution and we derive an upper limit for the ratio Γ_γγ⁽⁰⁾/Γ^γγ. The absence of events in the mass region around 1.3 GeV clearly proves destructive f₂-a₂ interference and allows to measure the relative phases between f₂, a₂ and f₂^′. Upper limits on the production of the glueball candidate states f₂(1720) and X(2230) as well as the K_S⁰K_S⁰-continuum are given.
